RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:

As documented, SSLSocket.getpeercert() should provide access to the Subject Alternate Name field from the peer's certificate.  A bug in python will result in the Subject Alternate Name field to not be available to the application.

This could cause a false authentication failure if the application performs certificate hostname checking.

Version-Release number of selected component (if applicable):

python-2.6.6-36

How reproducible:

100%

Steps to Reproduce:
1. python client connects to SSL server which has a SAN in its certificate
2. Have python access the certificate via getpeercert()
3. The returned map should have an entry for 'subjectAltName'
  
Actual results:

No entry for 'subjectAltName'

Expected results:

The map contains a 'subjectAltName' entry with a value that matches the SAN from the peer certificate.

Additional info:

The fix for this bug is straightforward, and has been fixed upstream in 2.7.3.  See http://bugs.python.org/issue13034

This patch will work ok with RHEL 6 Python 2.6.
